Back in April 2017, Serbian makeup artist Milan Bauranov posted a snap on Instagram (above) where he literally glued needles to a model's eyebrows, in addition to using products from Kat Von D's makeup line.

No one said boo about the beauty product at the time, but now the liner — named for the Green Day song and even featuring Billie Joe Armstrong in the advertising — is getting the wrong kind of attention.

An Instagram user calling herself Holly Quinn laid out a case against Kat as making light of mental health issues and specifically exploiting the images of Sid Vicious and Nancy Spungen, punk idols who infamously suffered from mental illness — and died violently in their early twenties.

The punk fan's message was clearly enough to raise Kat's hackles, as she commented on the post (below):

Following their "vintage" tee drama where they superimposed their faces over the likes of Tupac, Pink Floyd, Metallica, Kiss, The Doors, and Black Sabbath,the duo have the Internet heated with the way they're styling a plaid shirt from their Kendall + Kylie line!
